I have been working on my own header for quite some time for my curriculum vitae with modencv. Therefore I edited the command \makecvhead. I used the commands directly from moderncvheadii.sty. Nevertheless I get the following error message: "! Undefined control sequence. <argument> \makecvheadpicturebox".

I would also like to insert a footer again, but I can't do that with \makecvfooter.
